[binutils-gdb] Initialize variable and silence GCC warning from last commit

commit ad1c917a79e8c5aa67657f148415c1bee01b240f

    Initialize variable and silence GCC warning from last commit
    
    BuildBot e-mailed me to let me know that my last commit broke GDB on
    RHEL-7.1 s390x.  On solib-svr4.c:svr4_handle_solib_event, 'val' now
    needs to be initialized as NULL because it is inside a TRY..CATCH
    block.  This patch does that.  Pushed as obvious.

    	* solib-svr4.c (svr4_handle_solib_event): Initialize 'val' as NULL
